Kernel update refusing to work - (kernel 3.2.0-39-generic)

Hi again

I have been unable to update my ubuntu kernel for a few weeks now, and at a loss what to do. i also had a separate issue with updates here, but I could tell it was separate because after I cleared that up my failing kernel update gave the same errors as before.

I'd never heard of depmod before. Is there something I should do with one of the files in /var/lib/dpkg ? like delete it so it re-generates?

In other threads OPs were told to use df -i or df -h to see if their /boot directories were full, but my hard drive is huge and almost empty, and I didn't do any fancy partitioning, everything is under / on the same partition.
